Engraving has no eraser

A layer of colour laid on wrongly can be covered. You wait for it to dry, put another on top, and the mistake stays underneath, seen by no one.

A line cut into metal cannot be covered. The material that has been taken out does not go back.

The difference looks obvious, and its consequences are not.

The order can no longer change

In painting, the composition can be corrected while the work is going on. An element moved by two millimetres, a shadow deepened, an edge softened: all of it can be decided halfway, because the surface forgives.

In engraving, every cut closes a possibility. The depth chosen for one line decides how its shadow will behave for good, and the line beside it has to answer to what has already been cut. The composition is not built step by step; it has to exist whole in the head before the tool touches the disc.

That is why the longest part of an engraving is not the engraving. It is what happens before it.

What a mistake means

On a dial, one wrong line does not mean one wrong line. It means a new disc.

There is no partial repair: metal can be polished locally, but polishing changes the way the surface returns light, and the mended place shows precisely because it is smoother than the rest. The eye catches the difference even when it does not know what it is looking for.

So the only honest repair is to take new material and work again everything that had already been cut.

What it does to the rhythm

A man who knows he cannot go back works differently. Not faster and not slower: differently.

The breaks are taken before the hard lines, not after. What is certain is cut first, and what is still being weighed is left for last, because an undecided line cut early governs all the rest. And the day stops when the hand starts to tire, not when the planned work is done, since tiredness does not show in the line being cut now, but in the one ten minutes from now.

Why it is worth it

Because it shows.

A surface cut by hand does not have the regularity of a printed one, and it is exactly that lack of regularity which makes it catch the light differently at every movement of the wrist. The mark of the tool stays on the dial. Smoothed away, it would erase the very proof.
